"If suicide is a crime, only cowardice can drive us to it. If it is not a crime, both prudence and courage should lead us to rid ourselves of existence when it becomes a burden. If that time comes, suicide is our only way to be useful to society—setting an example which, if imitated, would preserve to everyone his chance for happiness in life, and effectively free him from all risk of misery."
